The Best and Worst Burgers

Worst drive-in burger

Sonic's Ring Leader Loaded Burger

For the most part, fast-food restaurants fared pretty well on our best and worst lists; their patties tend to be smaller and not as juicy (read: less fatty) than a lot of the diner or bar-and-grill chains. But, of course, there are exceptions.

With just one pattyplus bacon, cheese, a fried onion ring, and mayoSonic's Ring Leader Loaded Burger manages to pack in 1,230 calories, 86 grams of fat (28 grams saturated), and 1,230 milligrams of sodium. What's even worse? You can also order it as a double.
